SPECIFICATION forming part of Letters rarest No. 656,046, dated August:14, 1900.

- Application filed M y18,-1899.

To all whom it may concern.-

Be it known that we, PETER ULRICH RIESS and ANNA MARIE :J ULIE mass, of the .city of New York, (Williams Bridge,.borough of Bronx,) i n the county and State of New York, have invented certain .new and useful 1mprovements in Marine Vessels, of which the followingis a full,clear, and exact description.

The invention relates to m anually-propelled marine vessels; and its object is to provide a new and improved marine vessel which is simple and durable in construction and ar ranged to have its propelling-gear actuated by one or more persons in a very effective manner and without undue exertion, the construction permitting a convenient reversing whenever desired.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of our invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal sectional elevation of the improvement. Fig. 2 is a sectional plan view of the same on the line 2 2 in Fig. 1. Fig. 3 is an enlarged sectional side elevation of the propelling-gear.

The boat A,on which theimprovement is applied, is provided with a hold or open central space A for the accommodation of the occupants and the location of the propelling-gear, and near the bottom of the hold A is arranged a longitudinally-extending propeller-shaft B, carrying at its rear outer end a propeller C, and on a portion of a shaft within the boat is arranged a sleeve D, journaled in suitable bearings E, bolted or otherwise fastened to the bottom of the boat A. On the sleeve D is secured one, two, or more worms F, each in mesh with a Worm-wheel F secured on a transversely-extending crank-shaft G, carrying crank or pedal arms G and journaled in bearings held on brackets G secured to the bottom of thehold A and supporting-seats Gr for the operator, to permit the latter to conveniently actuate the pedal-arms with his feet to impart a rotary motion to the shaft G.

fierial No. 7l7,298; (N0 model.)

the sleeve D to the propeller-shaft B, We provide' the following mechanism: On the forward end of the sleeve D is secured a bevel gear-wheel H, in mesh with a bevel-pinion H, secured-on a vertically-disposed short shaft I, set .with its lower pointed end in a step E,

carried by a bracket or bearing E secured to the bottom of the boat. The upper end of .the shaft I is countersunk to be engaged by a center I, screwing in a nut 1 secured to a seat A extending transversely in the boat and attached to the sides thereof. On the shaft I, directly under the seat A is secured a fly wheel .I, and on the lower end of said shaft is fastened a bevel gear-wheelK, adapted to be engaged by either of the bevel gearwheels L or L, located at opposite sides of the bevel gear-wheel K and secured to the shaft B. On the shaft Bis formed an annu lar shifting-collar B, engaged by a shiftinglever N, connected by a link N with the handlever N under the control of the operator, to impart a sliding motion to the shaft B and the gear-wheels L L to move either of the said gear -wheels in mesh with the bevel gearwheel K.

Now the rotary motion of the sleeve D is transmitted by the gear-wheel II to the pinion H to rotate the shaft I, and the rotary motion of the latter is transmitted by the bevel gear-wheel K to the gear-wheel L or L in mesh at the time with said gear-wheel K, and as the gear-wheels L L are secured on the shaft B it is evident that the latter is rotated, and consequently the propeller O, to propel the boat either forward or backward, according to which of the gear-wheels L or L is in mesh at the time with the bevel gearwheel K. A suitable locking device, such as a notched bar N secured to the seat A", may be employed to lock the hand-lever N in the desired position.

It is evident from the foregoing that when the operator or operators actuate the pedalarms G a rotary motion is given to the shaft I by the gearing described, and as this shaft I is provided with a fly-wheel J it is evident that a steady uniform motion is transmitted to the propeller-shaft I to properly rotate the same.

We do not limit ourselves to the special construction shown and described for shiftin g the bevel gear-wheels L L, as other means may be used, if desired. The fly-wheel J is preferably located under the seat A to be out of harms way.

In front of each seat G is arranged a suitable handle-bar G adapted to be taken hold of by the operator for his convenient support on the seat G and one of the said handle-bars is preferably made to turn and is connected with the ropes or chains of the rudder or steering-gear, so that one of the operators can manipulate the steering-gear Without interrupting the work of propelling the vessel with his feet.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A manually-propelled gear for marine vessels, comprising a propeller-shaft, a sleeve through which passes said shaft, a foot-actuated driving-gear for said sleeve, and a gearing between said sleeve and said propellershaft, substantially as shown and described.

2. A manually-propelled gear for marine vessels, comprising a propeller-shaft, a sleeve through which passes said shaft, a foot-actu' ated driving-gear for said sleeve, a gearing between said sleeve and said propeller-shaft, and comprising a bevel gear-Wheel on the sleeve, a bevel-pinion in mesh with said bevel gear-wheel, a fly-Wheel shaft carrying said pinion, a bevel gear-wheel on said fly-wheel shaft, and two gear-wheels mounted to turn with the said propeller-shaft, and adapted to be moved into and out of mesh with the gearwheel on said fly-Wheel shat" t, substantially as shown and described.

3. A manually-propelled gear for marine vessels, comprising a pedal-actuated crankshaft, a worm-wheel on said shaft, a worm in rnesh With said worm-Wheel, a sleeve carrying said worm, a propeller-shaft extending through said sleeve, and a gearing between said sleeve and said propeller-shaft, substantially as shown and described.
